Official voting for the 2010's Game of the Decade will end Wednesday, December 27 at 11:59 PM, EST.

Witcher 3 or Breath of the Wild for me. Too difficult to decide at the moment. These are the two single player games I’ve played the most this generation.

Super Mario Galaxy 2 would be bronze, as I enjoyed that one quite a lot too… in fact, for level design and level fun, more than the first SMG.

The Last of Us is the game I haven’t played that I’m most interested in playing. It looks extremely good.

Breath of the Wild for the win, Super Mario Galaxy 2 runner up. Easy peasy.

That is a difficult one, but I have to go with BOTW. Just such an incredible experience.

Breath of the Wild is most likely going to win, but for me it's not even close to the best game of the decade. Fortunately, this time my actual game of the decade made it this far in the voting, that being Dark Souls.

I voted for TW3, but it's basically in a tie with Doom. I can also make a case for BOTW.

I've played all of the others, except for Journey, and I really can't wrap my head around why any of them would belong in the conversation. They're all good games, but games of the decade?  No way! 

Of these, I only voted for The Legend of Zelda Breath of the Wild and Super Smash Bros. Ultimate.

I mentioned in the 2018 thread, that while I liked it and it is a good game, I did really only vote for Smash in that year because there wasn't anything better. Breath of the Wild though, is a modern classic. Genuinely the best game of that year, and also if you asked me better than the other year winners I voted for. My vote for best of the decade is without a doubt The Legend of Zelda: Breath of the Wild.

Thanks The_Liquid_Laser for this series of threads!

I don't think I'm qualified to vote. Of the three games I've played, two are massively overrated (in my opinion), The third one (Journey) is great, but the game of the decade? No, just no. I would probably vote for The Witcher III or Breath of the Wild, but I haven't played either of them (yet!), so that wouldn't be the greatest thing to do. I'll reserve judgement until I've played more of the candidates.

Considering more traditional games, and discarding things like PUBG that popularized BR games...

I would say Dark Souls. The game that, coming from demon's Souls, created an entirely new genre and influenced several games, including big names like The witcher 3 and God of War. Dark Souls is the game of the decade, it will be remembered as the beginning of a genre that is becoming increasingly popular, possibly an immortal classic with tons of replay value.

Definitely won't win but Tropical Freeze is genuinely one of the most creative and fun platformers I've had the pleasure of playing...ever. Really a shame it didn't get that much of a spotlight.
